[Studio] Make Course Collections Available To Students

Problem statement:

People with the teacher role can see the "Studio" button in the course navigation column. This brings the teacher to a single pane of glass to see all of the Studio content published in the course. Students don't have the ability to see that button in the navigation column, and thus cannot see an aggregated view of all the content published in the course.

Proposed solution:

Allow students to see "Studio" in course navigation, so they can see all the videos published in the course. Even better, make the product more flexible, and allow me to add media in "My Library" directly to a course collection, rather than needing to add it to a part of the course.
